Post easyXLS cant process big files
I need to convert .xlsx to .xlsb file.
Size about 85Mb.
Script converts about 1.5 hours, then crashes:
Exception in thread "main" java.lang.OutOfMemoryError: GC overhead limit exceeded

and I already have set -Xmx8192m

I can open file by Excel manually and export it to xlsb, it takes about 3.5 minutes without any problems.
But we have requirement to convert files automatically in reporting system.

Hi Ildar! As per our conversation, please check these chapters in our online User Guide ... -file.html ... -file.html

You might also want to have a look at our preliminary tests for big volume data available at

If there is a big difference between our results and yours, please try to send us more details about how you are using EasyXLS.
